Seven Cities With the Cleanest Air in the World: A Look at Sustainability and Innovation

Air pollution is a pressing global concern, claiming an estimated 4.2 million lives prematurely in 2019 alone. The World Health Organization (WHO) emphasizes that almost 99% of the world's population resides in areas with air quality falling short of health standards. To address this critical issue, the WHO urges governments to prioritize policies promoting improved industrial practices, energy generation, transportation systems, city planning, electricity production, waste management, agricultural practices, and healthcare services.

The Seven Cities Leading the Way

While many regions struggle with air pollution, certain cities stand out for their exceptional air quality. According to airly.org, based on average PM2.5 levels measured over 12 months in 2022, here are seven cities boasting the cleanest air in the world.
